Agreed. I'm seeking confirmation, from IPTV implementers, that non igmpv3 support is the reason for using ASM with IPTV. Versus other reasons such as reducing state. Or is this a non issue and everyone is using SSM with IPTV?
We are running NG-MVPN (BGP replaces PIM, MPLS replaces IP/GRE). We run PIM-SM, not only because our customer's STB's only support IGMPv2 (we only transport IPTv content, not generate it), but also because, well, it just works and there hasn't been any compelling need to push for PIM-SSM. It's scaling well due to the nature of the NG-MVPN infrastructure itself. Mark.
